If you're going to mount a successful resistance movement, you ought to come up with some slogans to begin to educate people. Propaganda is an important aspect of your struggle and clearly, Anna knows how to sway public opinion. With an opponent like that you have to fight head on for the heart and minds of the people--both "visitor" and human. They should have shown the main characters doing so early on. They could have been out ahead of Anna's campaign to frame the Fifth Column as human terrorists.
For the human population, take advantage of the presence of visitors in your resistance and get some intel on their history, why Anna is a tyrant, how their own people don't all agree with what she's doing. Humans were heard saying more than once "But they haven't done anything bad!" Well, you need to tell them just what they've done! Draw on our rich history to illustrate your points. Trojan horse, anyone? It's not just a condom!
I'm sure that an anonymous website (with the usual bouncing off a zillion servers precaution, leading back to some neutral place eventually if traced) with an "Interview With A Visitor" that tells all the things Anna has swept under the rug would be a huge hit. Once that info is out many people will copy it and spread it. Part of that information should include the fact that visitors sent advance agents that have infiltrated every area of society in countries around the world. That is not the act of peaceful aliens! (Nor is showing up in your airspace without requesting permission in advance, but I digress.) We're not told what they may have done to other planets--that should be included.
Leaflets are a great way to appeal to the Luddites among us and are pretty hard to trace if you're careful. Leaflet versions of the interview can be distributed widely.
Posting some fliers in the usual places in town is also a good bet.
Will you convince everyone overnight? Of course not. But you'll plant seeds of doubt that might grow.
Some suggested slogans:
Beware of Visitors Bearing Gifts (with pic of Trojan Horse with soldiers spilling out in the night)
TANSTAAFL: THERE AIN'T NO SUCH THING AS A FREE LUNCH (Heinlein fans will immediately understand this one and the sci fi savvy audience is an important one--they've read enough to be a little more cynical about aliens)
If It Seems Too Good To Be True, It Probably Is
IF YOU'RE REALLY "OF PEACE" YOU WON'T NEED TO TELL EVERYONE ALL THE TIME
Who Pays For Their "Free" Health Care? What's Really In Their Vaccines?
Like Animals in the Wild, We're Being Tagged!
Why Couldn't the Visitors Ask Before Orbiting Earth? They Had The Technology. (pic of Independence Day aliens or ships or both) (the web site ought to have clips of the alien telling us to "die." )
FRIENDS DON'T LET FRIENDS MOVE INTO ALIEN SHIPS!
HAVE WE SEEN THE TRUE FACE OF THE VISITORS?
Remember "To Serve Man?" (CLIP OR STILL FROM MOVIE WITH THE LINE "IT'S A COOKBOOK!")
pic of Earth: PLANETS LIKE OURS ARE RARE AND VALUABLE--LET'S NOT GIVE IT AWAY TO THE FIRST ALIENS WHO VISIT
(PIC OF ANNA) PRETTY IS AS PRETTY DOES (followed by drawing of some of her worst actions behind the scenes, mentioned in the "interview" site)
(pic of Anna) Dangerous Things Come In Pretty Packages (followed by pic of...name your pretty and dangerous thing here ___________ ) [I can imagine lots of versions.]
JOHN MAY LIVES! (WITH SMALLER CASE BIO/HISTORY OF RESISTANCE)
Much of this could have been panned over in a video montage with one of those songs that are so popularly used these days. (I find this annoying myself.) It didn't even need to take up much screen time. It just would have made their resistance group more credible. I couldn't believe they'd cede the propaganda war to Anna right away.
It's a lot like a political campaign--don't let your opponent define you early on. Define THEM.
If humanity's survival is depending on it, I'd think you'd make it a priority. Even if you don't convince everyone to distrust the Visitors right away, you'll cause some to hesitate before going to a medical center and others will maybe stock up on supplies and weapons. You'll need them to be prepared later.
In general I've been frustrated with the writing of this remake. They've had their characters do some stupid things--some mistakes are even repeated. If our heroes are this dumb we should just fly the white flag right now. I also can't imagine our governments are all so naive that they allow aliens to open centers to give medical treatments they don't understand to their citizens. We've already got implantable GPS chips and other devices. Can't we guess that they have so much more?
I can't believe they renewed this and canceled other shows with better writing. I hate seeing these actors stuck with such bad writing.
Do you have a revolution you need slogans for?
